The Beach House, Jane Green.
This novel took place in Nantucket, MA, and now I want to move there! I've never been there but have heard it's beautiful. Something unusual about this book was that it was written entirely in the present - normal for a chick lit novel, but it was more just a "regular book" than chick lit. Jane Green has written a bunch of other novels as well, none of which I've read, but this book was a very good read - I finished it in a day or two.
